Said properposition to take its load is onerous in side bars extend forwardly andare secured the last degree, requiring the united and to the tongue '7,and upon the tongue and strenuous effort of two or more men.

The bail the device above described, bywhich the 0" is pivotally mounted in said pockets and draft of thesnatch team or teams is applied rocks therein, and extending rearwardlyhas directly to the scraperpan, it will be ohits ends pivotally securedto ears 9, mounted served that by reason of the bail having its upon thescraper-pan 10. A hand-lever 11 pivoted point or fulcrum fixed in thehangeris secured upon the bail, which, extending block the draft actsconstantly to draw the 5 forward, is adapted to be engaged by a springforward edge of the pan into the soil, so that latch 12, and therebysecured to retain the with such construction one man may easilyscraper-pan in elevated position to'carry its operate the scraper intaking theload.

' I mount standards 21, upon which are mounted spiral springs 22, whichsprings are connected with the scraper -pan conveniently by a link 23 onthe spring engaging an eye bolt 24, secured to the pan. The effect ofthis construction is that when the pan is let down to take its load'thespring is extended and under high tension, and when the loaded pan is tobe lifted the action of the spring facilitates the operation to suchextent that one man can easily do the work that without the spring wouldrequire the united exertion of two or three men. A further efficientfunction performed by said spring is to relieve the strain or downdrafton the necksv of the team attached to the scraper, besides and carryingthe tongue in this wise. It will be seen that the bail is mounted on thehangerblock in advance of the axle, so that when theload is taken andlifted up the weight of the load, as well as the weight of the men onthe platform required tooperate the scraper, is carried on the tongueand bears down upon the necks of the horses. This is a very seriouslyobjectionable feature in this type of scrapers. By providing aconnection with the scraper-pan to the rear of the axle, as herein shownand described, the load may be balanced over (or under) the axle to avery great nicety. Said connection is made adjustable by connecting thespring with an eyebolt 25,

passing through an extension 26 on the standard 21 and provided with anadjusting-nut 27. Another important advantage gained by the use of thespring is in'making the dump or dumping the load from the pan. In theusual construction when the dump is to be made the pan is let down; butthe greater part of the weight of the load being carried to the rear ofthe point of suspension of the pan on the bail the rear of the pan, withits load, must be lifted up until the forward edge of the pan is broughtinto contact with some obstruction sufficiently solid to stop the panand cause it to turn on its axis. device herein set forth when the panis let down the tension of the spring will hold up the rear of the panto such extent and in such manner that a very slight obstruction will besufiicient to tilt'the pan, thus very greatly facilitating the work ofdumping.

If desired,and particularly with the smallersized scrapers, the links 18may be connected with the bolt carrying the doubletree, as shown indotted lines in Fig. 6, the tongue in such case being slotted, as shownin dotted lines at 28, to permit movement of the doubletree toaccommodate the movement of the With the 4 pan as it is raisedandlowered, and thus,

when a'single team is used is gained the advantage of the application ofthe draft directly to the pan, and the leverage due to the relation ofthe draft-bars 15 to the bail, as hereinbefore set out.

Having thus fully described my improvements, whatI claim as myinvention, and desire to secure by Letters Patent, is-

1. In a wheeled scraper of the character described, a bail pivotallymounted in advance of the axle, a scraper-pan pivotally hung on saidbail to the rear of its point of suspension, a brace-bar connected withthe axle and supporting the rear of said pan, and the draft appliancesconnected directly to said pan whereby as the draft is applied theleverage of the bail tends to thrust said pan into the soil;substantially as set forth.

'2. In a wheeled scraper having its scraperpan carried by a forwardly-extending bail suspended from the axle, and provided with abrace-bar supporting the rear of said pan, draft-bars'conuected withsaid pan, and arranged in such manner that as the draft is applied thebail will act to thrust said pan into the soil, substantially as setforth.

3. In a wheeled scraper having its scraperpan carried by a bailsuspended from the axle and provided with a brace-bar supporting therear of said pan,draft-bars connected with said pan, and links connectedwith said draft-bars for the application of the draft directly to thepan; substantially as set forth.

4. A wheeled scraper comprising the wheels and axle, side bars connectedwith the axle and carrying the tongue, a platform mounted on said sidebars, a brace-bar supporting the axle, a bail provided with a hand-leversuspended from the axle, a scraper-pan hung on said bail, a brace-barconnected with the axle for supporting the rear of said pan, a latcharranged to engage said hand-lever when the scraper is raised up, andthe draftappliances connected with said pan whereby as the draft isapplied said bail will act to thrust said pan into the soil,substantially as set forth.-

5. In a wheeled scraper having its pan carried by a bail suspended fromthe axle and provided with a brace-bar connected with the axle forsupporting the rear of said pan, draftbars connected with said pan,links connected with said draft-bars, and a draft-rod connected withsaid links for the application of a snatch-team; substantially as setforth.

6. In a wheeled scraper having its pan carried by a bail suspended fromthe axle, and a platform carried by side bars connected with the axle,draft-bars connected with said pan, links connected with said draft-barsfor the application of the draft, and drop-bars pivotally mounted inbrackets secured upon said platform for supporting said draft-bars;substantially as set forth.

7. In a wheeled scraper having its pan carried-by a bail suspended fromthe axle, a rigid support stationarily mounted on said axle, and aresilient connection between said support and the scraper-pan;substantially as set forth.

8. In a wheeled scraper having its pan carried by a bail suspended fromthe axle, a rigid support stationarily mounted on said axle andextending rearwardly therefrom, and a resilient connection extendingfrom said support to said scraper-pan at the rear of the axle;substantially as set forth.

9. In a wheeled scraper having its pan carried by a bail suspended fromthe axle, and provided with a brace-bar supporting the rear of said pan,a resilient connection between the axle and said pan; substantially asset forth.

10. In a wheeled scraper having its pan carriedby a bail suspended fromthe axle, standards mounted upon the axle and springs connected withsaid standards and with said pan; substantially as and for the purposeset forth.

11. In a Wheeled scraper having its pan .pan, to the rear of the axle,substantially as and for the purpose set forth..

12. In a Wheeled scraper having its pan carried by a bail suspended fromthe axle, standards mounted upon the axle, springs connected with saidstandards and with said pan, and means for regulating and adjusting thetension of said springs; substantially as and for the purpose set forth.
